Kuyini inzwa lokushisa, futhi ziyini?

Inzwa lokushisa yidivayisi elula elinganisa futhi okungaqhathaniswa ezingeni inkomba kokupholisayo e injini ukushisa. Idatha etholwe nale divayisi ayanikezelwa i-electronic control unit (ECU), lapho okwenziwa futhi ibikwe computer ugibelile yesimo imoto. Kule ndaba, leli thuluzi ubhekwa obalulekile futhi zibalulekile, ngoba incike ke mode futhi injini ukusebenza.

Amafutha lokushisa inzwa inomthelela uhlelo lokulawula imoto injini ngokukhethekile. Ngokwesibonelo, ukubaluleka ishayela kokuvula Imibhobho esemzimbeni. Ngu ahlukahlukene, lolu ipharamitha Ungashintsha ukusebenza motor at ijubane lutho, petrol, ukubunjwa ingxube fuel nokuningi. Ngaphezu kwalokho, inzwa lokushisa sizothinta isikhathi ukuthungela, okuyinto, kuyobe ushintshe inani igesi qeda, petrol nokudludliza ukusebenza imoto. Isisu lemifanekiso uhlelo EVAP, ukubunjwa ingxube fuel, qeda gas recirculation, isivinini kokungenzi lutho - konke kuncike thuluzi ukufakwa ohlelweni ukupholisa.

inzwa lokushisa kuyinto thermistor eshintsha inani layo ukumelana lapho kushintshwa kokupholisayo kushiswa uhlelo injini. Okunjalo idivayisi ngokuvamile owawuba noma kwi-thermostat izindlu engayitholi ezininginingi noma inhloko isilinda. Icala lokugcina kuhilela ukufakwa nokubekwa izinzwa ezimbili, enye yazo i control unit electronic, futhi enye - ku fan. Noma samuntu kungenzeka yelungiselelo umbhangqwana amadivayisi ngamunye emabhuloki isilinda.

Engasebenzi kahle lokushisa inzwa kungaholela ukuwohloka okukhulu ukusebenza imoto egijima, kukhuphuke petrol, Ukuwohloka qeda gas Ukwakheka, kanye Ukuwohloka jikelele lokushayela.

Nokho, hhayi wonke umuntu angakwazi ngokushesha ukubona izici isici esibonisa ukwehluleka. Ngakho-ke, sonke lesi sihloko sizodingida izimpawu eyinhloko ukungasebenzi. Digital lokushisa inzwa ngomqondo obanzi kuyinto isisetjenziswa se-elektroniki. Lokho kuyinto kumadivayisi ambalwa zixhunywe inethiwekhi izintambo. Umphumela uba ukuthi inkinga eyinhloko wiring ezimbi, oxhumana kwakwakhe evulekile noma egqwalile. Ngaphezu kwalokho, indawo ekhethekile idivayisi ithatha thermostat. Uma luvuliwe, motor wehlisa Ukushisa, probe upha isitshengiselo esiphansi lokushisa motor. Esimweni lapho umshini othile kungahlali imodeli of imoto yakho, noma awusebenzi, izophinda isinyathelo amasignali ukuthi injini akukafiki yokusebenza lokushisa namagugu.

Thola ezikhona lokushisa inzwa iphutha can nge ngokucophelela wokuhlola ezibukwayo (nokugqwala, zokugwema ukuphuka wire) noma ngesikhathi ukudlula uphethwe ikhompyutha.
